Class FLoad

java.lang.Object
  jef.dna.instructions.impl.InstructionAncestor
      jef.dna.instructions.impl.FLoad

All Implemented Interfaces:

java.lang.Cloneable, Instruction, BytesCountable

public class FLoad
extends InstructionAncestor

This class maps the FLOAD bytecode instruction which loads a float value from a local variable whose index is provided as parameter. The float is then pushed on the top of the operand stack.
